Hello everyone!
I tried to enable cedrus264 encoder/decoder on my old OrangePI Lite 2 (revision 1 if I am right).
I used stulluk's repository as the base to patch the last FFMpeg revision and to add cedrus264 encoder using the new FFMpeg API. The result is built and tested. Unfortunately, I have had no success: the encoder says:
ffmpeg -f video4linux2 -input_format mjpeg -video_size 1280x720 -i /dev/video1 -c:v cedrus264 -pix_fmt nv12 -f mp4 video.mp4

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
It seems the encoder is not enabled in the Armbian kernel 5.10.60-sunxi64 because the device descriptor is not available.
However, I will be glad to see the code reviews, test results and any other feedback. Sorry, but I am not so familiar with FFMpeg API to send pull requests.
Please visit the FFMPEG fork repository here, the default branch is cedrus264:
